## Install

Before anything, you need to have [node](http://nodejs.org/) and [npm](https://www.npmjs.org/) installed.

```sh
$ npm install calendario
```

## Usage

Currently there are only **national** calendars (except for Brazil and U.S.A). In next release will be added regional support.

**Available for:**

- Brazil `.use('BR')`
  - [See usage for brazilian states](docs/BR/states.md)
- United States of America `.use('US')`
  - [See usage for U.S. states and territories](docs/US/states.md)

You can set the calendar using `use()`

```javascript
var calendario = require('calendario');
calendario.use('BR');
```

Setting the calendar for a specific state

```javascript
var calendario = require('calendario');
calendario.use('US-NY');
```

You can create your owns calendars, passing a array of objects like these:

```javascript
var calendario = require('calendario');

calendario.use('MozillaCalendar', [
	{date: new Date('2020-11-25'), workday: true, summary: "Mozilla Summit"},
	{date: new Date('2021-1-20'), workday: true, summary: "Mozilla another event"}
]);

calendario.use('GoogleCalendar', function(set) {
	set([
		{date: new Date('2017-6-3'), workday: true, summary: "Google IO"},
		{date: new Date('2018-10-5'), workday: true, summary: "Google another event"},
	]);
});
```

You can create your own calendar, passing a `ics` file

```javascript
var calendario = require('calendario');
calendario.use('BR', {file: 'pt-br.ics', parser: 'ics'});
```
